To all whom `it may concern: i

Be it known that I, ALBERT E. COOK, of the city of Odebolt, county of Sac, and State t of Iowa, have invented certain' new and useful Improvements in MotorPlows, of which the following is a full, clear, and ex- 'act specification, such as will enable others skilled in the art to which it appertains to make and use the same. V

The object of my invention is-to rovide v an organized apparatuswhich wil, by a single movement o'ver the ground, perform all the operations necessary1 to the complete cultivation of the soil, so t seeding and harrowing attachments maybe applied to the machine, as tparts thereof, and by a single operation o the machine over sodded or stubble ground, the sod or stubble will be sliced or cut, the ground will be plowed in furrows, the furrowed ground cultivated, the seed planted in the cultivated ground and the seeded ground harrowed,

tlius completing `in every part, the work necessary to the cultivation and seeding of the soil, leaving the next o eration'only the growing of the crop .an its subsequentI harvesting. The advantage of this will be obvious. In attaining this end, I- provide a frame on-which a motor or other source of power is mounted. The frame is supported on the ground by gangs of rotary disks or equivalent devices, arranged respectively at the front and rear of the frame and one or more, preferably all, of these disks are geared with the motor to be positively driven thereby, the disks being so arranged that they exert a. combined propelling and cultivating action, sending the machine forward and simultaneously cultivating the soil. Between these gangs of disks are arranged one -or more plows, whichare supported on the at, for example,

and thereupon the seeders and harrows operate toseed and harrow the soil. A

My. invention linvolves other features of importance allv of which will be fully set forth hereinafter and-vparticularly pointed out in the claims.

Reference is had to'ftheyA accompanying drawings,' whch`, illustrate, an example, I one manner-1n which` .the various elements may be embodied,.in which drawings, A

Fig-ure -1 is a. planview o fan apparatusI embodying'tlie preferred or most'complete form of my invention; Fig. 2 is a Side elevation'th'ereof'; Fig.A 3 is a detail sectional Aelevation showingthe gearing for raising and lowering the plows; and Figs. 4 and 5 are respectively, plan and sectional elevations of theclutch mechanismvfor operating the gearing 'shown in Fig.,3,

1o i dienaar. frame? hugh may be of anydesired constructionV and'on which the motor 0r engine'll, also of nyv'd'esiredform,

-,is 4mounted.E 'Atthe frontl of theframe,

according to the structure, shown iii' the drawlngs, arearranged twoAv angsof disks l2 set at an obligue an le, o eachv other,

and 'at thev rearpM gangsld are arran ed. These .gangs of disks 12 and 14 may e arranged'and operated in anydesired manner. For example, substantially as shown in the prior patent to Cook and Kurtz, No. .789,528 granted. Ma 9,1905; and -such general arrai'igementL is lustrated inthe1d:aw-ings,wliere 15 inldicatesithe vertical centers around which the gangs are-adjustableto control the operation of the disksand steer the plow, and 16 indicates the chains or .cables and drums by which thisv adjustment is effected., I desire it understood,fhowever, that my. invention is notlimitedto this particular arrangement. The shaft-,'17 of the motor runs longitudinally ofy the frame and is connectedat its ends with the respective gangs of disks by gearing 18 vwhich may also be the same as in the prior vpatent referred to or vof any other suitable nature.l In .this mannerthe gangs ofdisks are driven positiyelyfrom the motor and. serve notonly to cut thesod or'stubble and cultivate the ground, but also as the sole ropelling means of the plow.

Arranged) below 4the frame, intermediate its ends, and between the front and rear the. rame, two similar gangs of disks are a nizuiiberol plow shares i 19.' These are preferably arranged in two oblique gangs, themei'nbers of each of which have their beams 20 secured to bars'2ll which are vertically adjustable' with the plows ilrl guides 22 depending from the frame l0. By thus'raising or lowering the vbars2 1,"`t ,he plows `may be engaged with or disengagedI from the aground: This enables"the appa ratus to be readily adjusted so that the'plows may be lowered into operation orraieed to allowthe apparatus totransport itself` from t point to point or to allow the disks to operf ate in the soilrto the exclusion of thelplo'w's.

ThisA varied operation of'the 'disks is con-' trolled by. their .obliquity to the line' of. movement of the apparatus, their cultivab. ing action decreasingas theyare moved. to'- ward planes parallel to the line' of Vmovev2g ment, unt-il when parallel tojsuchrlin-"of' movement, the disksoperate as wheels "only, and the apparatus propels itself over the ground with no cultivating action.` ,f

For raising and' lowering'y the :plows x19 erence, 'the owerof the endinelderived fromI the shaft l land-controlled and applied by' a siiitable gear all of which will now-4 liefdescribed. 0n the shaft l? anesplinedjalten' sovnately acting clutch collars connected.l with -levers 'Of thelq'slg'iie is' a hand lever and"fiscrossconneeted lby Au link 24 with the otlieizf' Coactingwith'the clutch collars 2 3 aremit'erg'ears .,25fwhichl are held loosely on the shaftand have clutch teeth adapted to inter-engage with those on the clutch collars. The miterz geai'sl25.l are in mesh with two similar gears 26-1Ywhich V arereslpeetively fasten shaftsections A27 4o rotatab y'rnounted transversely on the frame j 1'0. 'lheshat'` sections 27 carry at'thei'r outerends .ruiter gears 28' which arev meshed with gears -29 held to rotatevin boxes '30 f mounted ontheframe 10 andfengaged with the hubs 4of theI gears sc thatthey may rotate freely, v'hutwill lie-'incapable'.of A.axial motion. The gearsg29" arecentially bored and internally fthfggded to serve aslnuts and o crate as'suohonscrew 'shafts '31 attached: 5o rigidly to the 'hars' A2 11and'-rising therefromv thr openings. in the frame 10. Bylopei-at ng'the lever's24, the gears 25 may be driven at willfrom the shaft'l'? thus driving the elements '26, 27, 28 and 29 and, fromthe 'S afts .31 toniovejupor'down. It will be seeninf this connection that the direction `of movementof the'screws 31 and their comv neet-ions is'd terinined by the direction of motion of th :levers 24, motion in one di'- A A rection throwing one clutclrin action anda,

rotating the gears' 26 in one direction and motion of the levers .thefoth'er direction reversing this action. 'I`i i"5:'onipensate for #65., the" opposite directionso'f'- rotation ofthe bis gears 26 and their connections, the shafts 31 are right and left threaded, thereby, insuring that the two gangs of plows 19 Aare simultaueously raised or lowered.

Y- Adjacent. to"'th'e 'gangs of disks 14 are 70 arranged seeder devices 32. These may he of any desired construction and are arranged to plantf't-hesee'd in the furrows rearward ofthe disks-14'. Behind these seeder devices are arranged harrow teeth 33, which after the rvseed is planted, harrow the soiland leave the same ready for 'the seed' to sprout and grow without further cultivation.

the 'o ration ofthe apparatus, the gangs of dig/ks 'working along relativelv 8o oblique axesexert a propelling force tendving to send the plowstraight ahead. The plowingfaction, andthe direction of motion of the plow',f'may becontrolled by changing the angularity.- ofthe disk gangs,'suitable '85 mechanismsrbeing' rovided for this Apurpose, a's'will,.;iin erstood from the prior patent mentined.. -As the a paratus moves over the ground', 4the front diskslcut or slice *the sod, stubble,.etc. and are followed by the lplows'whichfturn the. lThe specific form ofthe plows is, immaterial. They are here shown as of. the landside andv inoldboard type, butmay'be ofthe disk type if desired'. The real; disksfollowing'jlthe plows, culti 95 vate thesoilhieaking it, u and leaving it fg. readyfor the reception of tve seed. This is drilled into the ound bythe seeder devices i and `following t is the ground isharrowed by the spring teeth. Thus, bya sin le mech- 10o anism, and a single o ration, t e entire work of cultivation is ected, excepting; of course,-the harvestingofthe cro Iti'isfto be noted in this connection that t e plowingmeans by their natiral action exert a downward suction, oij'fdrgiitonthe entire appae ratusdrawi th ldisksor 'othersupportl ing and prope lingl neans firmly against the ground. `This downward draft engages'the l. propelling means firmly with the earth and no supplies the tracticln, at the same time allow; g ing' the machine to be light-ly constructed ,-i without de ndingupon its-weight .for its traction. is feature is effjlgreat' n nportance'since it admits ofthe use ofaininim'um 115 of. material and the expenditure`` of' a minimum ofenergy in accomplishing' the result in hand, that'is-to say, it requires Aless power -toi propel a lig-)htly-'const'ijucted apparatus than one more eavily constructed. nlthis 'pition the weight of the earthen.
